Left sidebar 2

This page-template is the same as the left-sidebar template except for one thing: 
The stacking order on mobile devices is reversed. (main-area stacks on top sidebar-left)

This is helpful if you have for example a navigation placed inside the sidebar. On mobile devices the navigation comes after the main content so the user doesn't need to scroll past the navigation to see the main content. 

This cannot be achieved with the grid framework.
